KANAZAWA, Japan, Feb. 8, 2021 /PRNewswire/ In a study published in
Nature Communications, cancer researchers at Kanazawa University identify mechanisms by which malignant tumor cells extend their toxicity to distinct cell types and in turn help them spread.
Most tumors consist of a heterogenous mix of cells. Genetic mutations found only in some of these cells are known to aid with the spread and progression of cancer. However, oncologists often find that when tumors metastasize to distant organs, they retain this heterogenous nature a phenomenon termed polyclonal metastasis . The mechanism by which non-metastatic cells accompany the metastatic cells is ambiguous. Now, Masanobu Oshima and his research team have used mouse models to explain how non-metastatic cells begin their long commute.

KANAZAWA, Japan, Jan. 21, 2021 /PRNewswire/ Researchers at Kanazawa University report in
Clinical Cancer Research that in the most common type of lung cancer, certain secondary mutations occurring with another gene alteration known as ALK make the efficacy of alectinib, an otherwise commonly used drug for treating lung cancer, become unfavorable. Combining alectinib with another kind of drug can overcome this adverse effect, however.
Most lung cancers are of a type called non-small-cell lung carcinoma (NSCLC). This type of cancer is relatively insensitive to chemotherapy, so NSCLC therapies are usually based on drug treatment. Alectinib is a drug commonly used for treating patients with NSCLC. It addresses a gene rearrangement known as ALK that occurs in 3 to 5% of NSCLC patients (alectinib belongs to a class of drugs called ALK tyrosine kinase inhibitors). It has been unclear, however, whether there is a correlation between the use of alectinib and the poore
